I am having a problem with my desktop randomly freezing. The problem can occur at any time, with seemingly no pattern to it. I canít reproduce the problem through any sequence, it just happens on its own, perhaps once or twice a day.
When it crashes the computer instantly freezes up, if there is any music playing it freezes at the same time and the speakers or headphones loudly buzz for about 10 seconds or so before they go silent. If I leave the computer in this state I can hear one of the fans slowly speeding up after a minute or so. There are no blue screens or any error messages, it just freezes. The computer can only be brought back to life by a holding the power button down to get it to restart. When I restart the computer everything appears to work as normal.
I assume it is either a temperamental component or a piece of software which I have installed. If it is of any help my desktop set up is:
AMD Phenom II X4 810 2.6 GHz Processor
Acer FRX780M Motherboard
6GB Samsung RAM (2 x 2GB and 2 x 1GB)
ATI 4870 1GB Graphics Card
Western Digital 640GB Hard Drive (OS and Programs)
Hitachi 1TB Hard Drive (For files)
The system is kept fully up to date, and I use Microsoft Security Essentials as anti-virus.
I have tried everything I can think of; including wiping the machine using my retail Win 7 Pro install disc, and reinstalling software, and the problem is still there. Iíve had it open and cleaned it and checked the connections and they all seem to be ok.
Any help or suggestions greatly appreciated.
